权限控制代码：
/**
* 基控制器
*/
public class BaseController {
//log4j2
protected Logger logger = LogManager.getLogger(BaseController.class);
//获取管理员信息
protected Object checkAdmin(HttpSession session){
Object o = session.getAttribute("adminId");
if(o==null){
logger.info("无管理权限，返回管理员登陆页");
return null;
}
logger.info("当前登录管理员ID：{}",o);

}
//检查用户是否登录
protected Object checkUser(HttpSession session){
